Do you have an ohmmeter? If so test the coil coils. Are there 2?

2.2L (VIN 4) Engine
  1. Remove the ignition coil(s).

  2. Using an ohmmeter, check the resistance between the primary terminals on the underside of the coil. The resistance should be 0.50-0.90 ohms.

  3. Check the resistance between the secondary terminals. It should be 5000-10,000 ohms.

  4. If the coil failed either test, replace the coil.

Also, what is your battery voltage?
Customer: replied 4 years ago.
The battery voltage was around 11 to 12 i killed the battery alittle
Expert:  Mike S. replied 4 years ago.
Ok, when you charge the battery back up that might raise that coil voltage. Did you charge the battery back up yet?
Customer: replied 4 years ago.
battery was charged back up coils test ok the strange thing when we start it the headligt blink 2 times and still have no spark
Expert:  Mike S. replied 4 years ago.
No spark from where? The spark plug or coil? How many coils does that hve?
Customer: replied 4 years ago.
Has 2 coils 1 & 4 2&3 no spark to the wires both coils checked out with the test you ask me to do
Expert:  Mike S. replied 4 years ago.

Swap the spark plug wires that dont work with ones that do and see if the miss moves, if it does then the wires are bad.

A easy way to check for spark without having to pull boots or poke holes in them is use my cylinder balance test kit and test plug.

 

You can make a test plug with a new spark plug and some wire, a mini hose clamp and an alligator clip. First open the spark plug gap to around 0.075" and strip both ends of a 16 gauge wire about 4 foot in length. Attach the mini hose clamp around the threads of the spark plug cause that is a ground and secure it with the mini hose clamp with the bare wire end in between to make a good connection. Next, take the other end of wire and secure to an alligator clip.

Now, you have a test plug. Remove any spark plug boot you want and insert your test plug onto the spark plug wire end you just pulled off and ground the alligator clip. Lay the spark plug in some shade somewhere under that hood and then crank the engine and look for spark. It should crackle with sound and should be blue but red is ok, orange is a little weak. If it can jump that 0.075" gap you should have no problem igniting an engine.

You can also use that to check coils on some vehicles.

 

 

First of all you will need a 12-volt test light and about 8-12 inches of neoprene vacuum hose. The vacuum hose will conduct electricity cause it is carbon based, use an ohmmeter if you aren't sure and see if the vacuum hose you have will conduct.

Now, cut off the same # XXXXX cylinders you have in small equal lengths of the vacuum hose. 1-2 inches will do fine. The small diameter kind like to carburetors, etc will work as long as they fit over the distributor cap tower connection.

Now, mark all your spark plug wires at the cap and remove them all. Put those short pieces of vacuum hose on the distributor cap connections and shove the other end of the vacuum hose into the spark plug wire boot until it makes a good connection.

Now connect your 12 volt test ground clip to a ground and start the vehicle. With the engine running touch the 12 volt test light to each of the vacuum hose 1 at a time and listen for the cylinder to short out and die and drop in r.p.m. They should all be about equal. If 1 or a few don't drop or do anything than you have your dead cylinder there.

Sorry misunderstading the car still wont start wire is were i checkd for spark car turns over but will not start
Expert:  Mike S. replied 4 years ago.
Ok, use the test plug to test for spark. Save the cylinder balance test for later. If you have spark coming out of the coil it is either bad spark plug wires or the plugs are fouled, that is why I asked for you to swap the wires around and then check for spark.
Customer: replied 4 years ago.
I Checked the coils and power going into them 12 volts is at the plug it seem to have something to do with ingnition control or crank sensor ?
Expert:  Mike S. replied 4 years ago.

I belive you may need a ignition module. Its under the coils. I believe most auto-parts stores have testers for the ignition module. The crank and cam sensor helps to time the engine the spark is created from the ignition module. You may want to have that tested. It is quite expensive.

REMOVAL & INSTALLATION

2.2L Engines
  1. Disconnect the negative battery cable.
  2. On 1995-97 models, raise and safely support the vehicle.
  3. Remove the ignition coils from the module.
  4. Remove the module from the assembly plate.
  5. Installation is the reverse of the removal procedure.
    Fig. 1: The ignition module or (ICM), is located under the coils

    Fig. 2: The ignition coil/module location - 1998-00 2.2L engines

Expert:  Mike S. replied 4 years ago.

You can test the other sensors.

Crank sensor

TESTING

  1. Turn the ignition key OFF.
  2. Unplug the sensor electrical harness and check the terminals for corrosion and damage.
  3. Check the sensor wiring harness wires for continuity and repair as necessary.
  4. Attach the sensor harness making sure it is firmly engaged.
  5. Using a Digital Volt Ohm Meter (DVOM) set on the DC scale, backprobe the sensor signal terminal (terminal A) with the positive lead of the meter and backprobe the sensor ground terminal (terminal B) with the negative lead of the meter.
  6. Have an assistant crank the engine and observe the meter.
  7. You should have approximately a 5 volt reference signal pulse. If not the sensor may be defective.
    Fig. 1: Attach suitable jumper wires between the CKP sensor and CKP sensor harness. A DC volt meter can then be attached to the necessary terminals to test the sensor as the engine is being cranked

cam sensor

TESTING

  1. Remove the PCM fuse to prevent the engine from starting. Removal of the PCM fuse does not disable the sensor power supply and allows testing of this sensor safely.
  2. Disconnect the CMP sensor wiring harness and attach suitable jumper wires between the CMP sensor and CMP sensor harness. Connect a DC volt meter to the jumper wires corresponding to CMP IGN or PWR terminal and sensor ground.
  3. With the ignition ON and the engine off, verify that the voltage is approximately battery voltage. The supply voltage should be slightly less than battery voltage.
  4. If not as specified, repair or replace the fuse and/or wiring.
  5. Connect a DC volt meter to the jumper wires corresponding to CMP signal terminal and sensor ground.
  6. Place a socket and breaker bar or the crankshaft pulley bolt and rotate the engine slowly by hand. Observe the volt meter and verify that the voltage signal varies from approximately zero volts to slightly less than supply voltage. The voltage will switch on when the target passes the sensor and will show little or no voltage when the target is past the sensor.
  7. If it is not as specified, the CMP sensor may be faulty.
    Fig. 1: Common Camshaft Position (CMP) sensor wiring schematic - 2.2L engines (wire color, terminal identification/location may vary on certain models)

    Fig. 2: Attach suitable jumper wires between the CMP sensor and CMP sensor harness. Connect a DC volt meter to the jumper wires corresponding to IGN and sensor ground terminals and note the reading

    Fig. 3: Connect the volt meter to the jumper wire corresponding to signal and sensor ground terminals, rotate the engine and observe the volt meter and verify that the voltage signal varies from approximately zero volts to slightly less than supply voltage

Expert JHoop says, the alarm may be locked-out.

 

This vehicle has a the GM ORIGINAL VATS key based
engine disabling system, and from the description,
it appears you've reset the VATS somehow.

This is a problem that won't just
go away either. It needs to be addressed soon.

The car does not recognise the chip in the ignition
key when that happens. When removing the power,
you inadvertently wiped the memory as well.

You can try to put the key
in the ignition, turn to the on position & wait at
least 10 mins like that when it happens, and that
MIGHT work. But after awhile, it will stop working at all.
Your ignition switch VATS reader assembly may be to blame.

In some cases, the VATS (GM'S VEHICLE ANTI THEFT SYSTEM)
will re learn the code this way, and will then
allow the restart all the time. But if this does not work,
then go to any GM vehicle dealer to have the service department
evaluate the issue, & re code it.

Good luck I hope method 1 does the trick!

Trouble Code: (2.2L L4 VIN 4 Auto)
Theft Deterrent Fuel Disable Signal Received
Print this code dataPrint This Code

Number of Trips to Set Code: 1

OBD II Monitor Type: CCM Details
Indicators: MIL Details

Trouble Code Conditions:

Engine cranking, and the PCM received a Fuel Disabled password XXXXX the Body Control Module (BCM), or an "undecided" password XXXXX sent from the PCM to the BCM. The VTD system (the Passlock II System) is designed to prevent vehicle theft by disabling the engine unless a mechanical key is used to correctly engage the Passlock lock cylinder. This system utilizes a lock cylinder, ignition switch, the BCM and the PCM. When starting the engine, the PCM looks for a password XXXXX the BCM through the Class 2 serial data circuit. If the password XXXXX XXXXX recognized or not present, the PCM will disable the engine. If an incorrect or no Password XXXXX XXXXX this indicates that the engine will start and stall and the Theft System telltale will flash on the IPC for 4 seconds. If an incorrect or disable password XXXXX XXXXX (more than three invalid passwords received) the engine will be disabled for at least 10 minutes and the Theft System telltale will turn to "solid" on the IPC for 3 seconds, and then flash on the IPC for 10 minutes. After the vehicle passes theft detection, the PCM will continue normal engine operation. If the PCM loses the BCM communication within the same ignition cycle, the vehicle will continue to run on the following ignition cycles. This mode is called the fail enable mode.

 

Possible Causes:

  • Perform the Powertrain Onboard Diagnostic System Check

  • Password XXXXX Procedure - Attempt to start the vehicle (leave the ignition "on"). The Theft System telltale will flash for 4 seconds and then remain "on" for 10 minutes. Theft System Learn Mode will display Disabled on the Scan Tool

  • Turn the ignition "off" after the Theft System telltale goes "out".

  • Repeat steps 1 and 2 two more times. After the Theft System telltale turns "off" on the 3rd key cycle, and Theft System Learn Mode will display Enabled on the Scan Tool, attempt to start the engine. Once the engine starts the password XXXXX XXXXX

 

Passlock Learn Procedure

 

NOTE

Due to component variability, the Vehicle Theft Deterrent (VTD) system must have the learn procedure performed regardless, if the vehicle starts on the first ignition cycle after a VTD repair.

 

 

NOTE

All codes in the theft deterrent module must be cleared for a relearn.

 

 

NOTE

The Body Control Module (BCM) must be programmed with the proper RPO configurations before performing learn procedures. Refer to BCM Programming/RPO Configuration in Body Control System.

 

 

NOTE

If replacing the BCM with a GM Service Parts Operations (SPO) replacement part, the module will learn Passlock sensor data code immediately. The existing PCM however, must learn the new fuel continue password XXXXX the BCM is replaced.

 

 

NOTE

If replacing a PCM with a GM Service Parts Operations (SPO) replacement part, after programming, these modules will learn the incoming fuel continue password XXXXX upon receipt of a password XXXXX Once a password XXXXX is received, and a password XXXXX XXXXX a learn procedure must be performed to change this password XXXXX A PCM which has been previously installed in another vehicle will have learned the other vehicle's fuel continue password XXXXX will require a learn procedure after programming to learn the current vehicle's password.

 

Use these procedures after replacing:

  • Passlock Sensor

  • BCM

  • PCM


 

10-Minute Learn Procedure
  1. Connect the Tech 2® scan tool to the vehicle.

  2. Select "Request Information" under "Service Programming".

  4. On the Techline terminal, select "Theft Module Re-Learn" under "Service Programming".

  5. Disconnect the Tech 2® scan tool from the Techline terminal and connect it to the vehicle.

  6. Turn ON the ignition, with the engine OFF.

  7. Select "VTD Re-Learn" under "Service Programming".

  8. Attempt to start the engine, then release the key to ON. The vehicle will not start.

  9. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or password XXXXX the next ignition switch transition from OFF to CRANK.

  10. Turn OFF the ignition, and wait 5 seconds.

  11. Start the engine. The vehicle has now learned the password.

  12. With the Tech 2® scan tool scan tool, clear any DTCs.

 

30-Minute Learn Procedure
  1. Turn ON the ignition, with the engine OFF.

  2. Attempt to start the engine, then release the key to ON. The vehicle will not start.

  3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.

  4. Turn OFF the ignition, and wait 5 seconds.

  5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.

     

    NOTE

    The vehicle learns the Passlock Sensor Data Code and/or password XXXXX the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

     

  6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password.
